lbcd

lbcd is a full node implementation of the LBRY blockchain written in Go (golang). It downloads, validates and serves the block chain, relays blocks and transactions, and maintains a transaction pool.

Note: lbcd does NOT include wallet functionality. That functionality is provided by lbcwallet and the LBRY SDK.

Requirements

Go 1.25 or newer. All common operating systems are supported. A node needs a fair amount of RAM and disk space, both of which grow slowly over time; a fast NVMe disk is recommended.

Installation

Binary releases are published at https://github.com/LBRYFoundation/lbcd/releases

Build from Source (Linux/BSD/macOS/POSIX)

• Install Go according to its installation instructions and check that it works:

$ go version

• Clone and build:

$ git clone https://github.com/LBRYFoundation/lbcd
$ cd lbcd
$ go install -v . ./cmd/...

• The node and its utilities are installed in $(go env GOPATH)/bin. Add that directory to your PATH if it isn't already there.

Updating

$ cd lbcd
$ git pull
$ go install -v . ./cmd/...

Getting Started

lbcd has several configuration options to tweak how it runs, but it works with zero configuration. See sample-btcd.conf for the available options.

$ btcd
